Since geotechnical exploration and pile driving are not exact sciences, it is often challenging to predict the difficulty of driving piles and also to determine what their final lengths will be. To assist engineers and contractors in the construction of deep foundations, pile splicers, shoes, points, and other accessories are available.

Pile splicers are used to splice steel, concrete, and wood piles. They are used in situations where final pile lengths need to be longer than what could otherwise be reasonably handled and delivered, or in low head room applications. Shoes and points protect the ends of piles, ease installation and, in the case of pipe, prevent soil intrusion so the pipe can be filled with concrete. Extruded corner piles are also available to ease construction of sheet pile walls. Pile accessories can be custom made to fit almost any requirement.
